'Tor-all 'whom it may concern Be it known that I, Oscar Bonner, a citizen oil the United States, residing at New York city, Manhattan, county oil New York, State of New York, haveinvented new and useful llmpxrovements. in Bottles or Rece tacles, of w tion. A This invention relates to an improved bottle or receptacle for liquids, etc., which is. so

constructed thatl said liquids retain their 'temperatures for a considerable length of time. Fort-his purpose the bottle isA pro videdwith double walls, between which a vacuum chamber is formed, and this invention relates, more particularly, tov novel means for permanentl sustaining the inner wall properly centere within the outer wall.

of the bot-tle. I have found that where such receptacles are used to contain exceedingly hot or cold liquids, it is necessary that the sustaining means be such as will permit of the expansion or contraction -of the inner vessel which necessarily occurs. At the same time the inner vessel must be held against lateral movement; otherwise there is considerable liability of the receptacle cracking at the neck. It is also desirable that the sustaining means be of such character and located in such manner as to support the weight of the liquid contained in the inner vessel; in other Words, the support should be so arranged as to cause the walls of both the inner and outer vessels tov coperate to this end.

By my present invention I obtain all of these valuable results, and in the accompanying drawing illustrating one form thereof Figure 1 is a vertical longitudinal section through my improved bottle; Fig. 2

. an enlarged section through the bottom thereof; Fig. 3 a detail bottom view of the tllriskband- Fig. 4 a cross section on line 4 4,

'Ihe numeral 10 indicates a cylindrical inner vessel provided with a curved bottom 11 and a contracted top or neck 12. Vessel 10 is inclosed within an outer vessel or casing 13, the shape of which corresponds, substantially, to that of vessel 10, vessel 13 being provided with a' curved bottom 14 and a neck 15. Vessels 10 and 13 are preferably made of a heat insulating material such as glass, and they are molten or fused together ich the following isa speci a' at the neck., as` shown in- Fig. 1, the size of the vessels being such, that a comparatively narrow chamber 16 is` formedy between them.

In ,order to sustain vessel 10 properly spaced from vessel. 13, and to avoid breakage-.of the inner vessel near its neck, l secure to the bottom of vessel 1.0, a dished disk 17 of metal or any other suitable material.

`Disk 17 is serrated at'its periphery, as at 18, and is provided with a central recess 1.9. The latter is engaged by a pro'ecton or lug 20 extending inwardly from ottoni 14. of vesselV 13.. Chamber 16. is evacuated, for which purpose vessel- 132 is 1arovided with a -teat 21 which is sealed a er the air has been exhausted from the chamber.

In manufacturing my improved bottle,

`the completed inner vessel 10 is heated at its bottom and disk 17 is pressed against said lbottom in such a manner, that the circumferential teeth 18 of disk 17 bite slightly into the softened glass without, however, penetrating through the same. Vessel 10 is then inclosed within the outer vessel 13 and the necks of both vessels are fused together. Bottom 14 of outer vessel 13 is now heated and when the same has become sutliciently soft, the apex of bottom 14 is pressed inwardly by means of a suitable tool so as to enter recess 19 of disk 17. Chamber 16 is' then evacuated and teat 21 is sealed.

Although a cylindrical bottle is shown in the drawing, it is obvious that the bottle may have any suitable shape, without departing from the spirit of my invention. The shape of the support or disk 17 may also be varied, but as shown in the drawings it will engage both the inner and outer vessels so as to prevent any relative lateral displacement thereof, while at the same time the inherent elasticity or resiliency of the metal support will permit of the necessary expansion or contraction of the inner vessel when a hot or cold liquid is placed therein. It will be seen that by the construction described, the inner vessel 10, of. my improved bottle, is properly centered and yieldingly supported within casing 13 without exercising any undue strain upon the parts, so that breaka of the bottle is avoided, even if the lled bottle receives concussione or shocks. By this construction, the weight of the liquid contained in the inner vessel is also, supported or sustained in part by the outer vessel, and thus the strength of the 'article is greatly increased.

It is obvious that many modications and changes may be made in my invention without departing fromthe spirit thereof, and I do no-t intend to limit myself to the particular form shown andl described, but

What I claim and desire to secure by Letters Patent is 1- l. A bottle of the character described, comprising any inner vessel having a curved bottom, an outer vessel having a curved bottom, and a sustaining, resilient metal disk interposed between said bottoms.

2. A bottle of the character describedl comprising an inner vessel having a curved bottom, a snrroundingouter `vessel having a curved bottom, a disk connected at its pe` riphery to the bottom of the inner `vessel, andmeans on the bottom of the outer vessel that engage the center of the disk.

3. A bottle of thel character described comprising an inner vessel having a curved bottom, a surrounding outer `vesselfhavin a curved bottom, a recessed disk connecte at its periphery to the bottom of vtheinner vessel, and a lug on the bottom of the outer vessel that engages the disk recess.

4. A bottle of the character described comprising an inner vessel, a recessed disk4 riphery that engages corresponding'indenta-A tions of lsaid bottom, an outer vessel having a curved bottom, and an inwardly-projectinglug on said last-named bottom that engages the disk recess. i

6. A vacuum insulated bottle comprising an inner and outer part, a support mount-ed between the bases of said'parts and means on the base of the inner part engaging said support to hold the same against displace,- ment in any direction independently of the ybase of the outer part.
